ALBERT WADKINS HARVEY, OF ROOKWALL, TEXAS.

RAILWAY-SIGNAL.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed September 9, 1907. Serial No. 391,967.

To all whom it may concern:

Be it known that I, ALBERT WADKINS HARvEY, citizen of the United Statesof ierlca, residing at Rockwall, in the county of Rockwall, State ofTexas, have invented certain new and useful Improvements inRailway-Signals, of which the following is a specification.

This invention relates to new and useful improvements in railway signalsand has relation more especially -to automatic signals for railroadcrossings.

It is an object of the invention to provide a novel device of thischaracter which performs its function through the medium of a trip whichis operated by the wheels of a train passing thereover.

It is also an object of the invention to provide a novel annunciatingmedium em loyed in combination with the trip which will hold the trip inits normal or vertical position.

It is also an object of the invention to provide in a novel device ofthis kind, means carried by the trip for preventing the trip fromassuming an inoperative position.

Furthermore, an object of this invention is to produce a device of thecharacter noted which will possess advantages in points of sim licity,efiiciency and durability proving at t e same time comparativelyinexpensive to manufacture.

With the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccom anying drawings forming part of this speci ication wherein likecharacters denote corresponding parts in the several views, in whichFigure 1, is a view in side elevation of a portion of a track showingthe trip mechanism ap lied thereto; Fig. 2, is a view in top plan simiar to Fig. 1. Fig. 3, is a view in detail of the trip mechanism.

In the drawings 1', denotes the rails of the ordinary construction whichrest upon the cross ties 2.

Mounted in the bearings 3, of one of the ties is the shaft 4, which isto the outer side of one of the rails and extends longitudinally of thetie. The inner end of this shaft has secured thereto the lever 5, whichextends up- 1 ward Vertically therefrom and terminates in the elongatedhead 6, which has its upper surface rounded. This head extends above thetacted with by the wheels of a train passing over the tracks 1. It willbe understood that tact, it will cause the shaft 4, rotate.

The opposite or outer end of the shaft 4, is provided with a dependingarm 7, to which is secured an end of a flexible connection 7 which isattached to a suitable annunciating means. Thus it will be seen thatwhen the shaft is partially rotated, a sounding device located at anysuitable point will be caused to operate.

The sounding device preferably comprises a gong 8, mounted on an upright9. The sounder of the ong is carried by a pivoted lever 10, which assecured thereto a strong spring 11, which is also secured to an arm 12,projecting incline. To this gong lever is secured an end of the flexibleconnection 7*. The strong spring 11, is of such tension as to partially6, to its normal position above the head of the rail after it has beendepressed by the wheels passing thereover.

In order that the tension of the spring may not carry the head 6, toohigh above the head of the rail, a stop 13, is carried adjacent the freeend of the head and extends laterally therefrom and is intended toengage with the under surface of the head of the rail, as will it isthought, be fully understood.

What I claim is 1. In combination with a railroad track and its crossties, a shaft mounted longitudinally of one of the ties, an arm fixed tothe shaft extending upwardly from the shaft and terminating above thehead of the carried by the arm to contact with the under surface of thehead, a second arm carried by the shaft, an annunciating means, and aconnection between the second arm of the shaft and the annunciatingmeans.

2. In combination with a railroad track and its cross ties, a shaftmounted longitudinally of one of the ties, an arm fixed to theterminating above the head of the rail, a stop carried by the arm tocontact with the under head of the rail and is intended to be con-- whenthis head is depressed by the said conto not only. return the gong leverbut to return the head shaft extending upwardly from the shaft andupwardly from the upright on an i rail, a stop surface of the head, theshaft, an annun a second arm carried by clatlng means, a connec- 5 inconjunction With said spring being rotate the shaft.

of sufficient tension tc In testimony whereof I tnesses this 3d day inthe presence of two Wi of July, 1907:

affix my signature ALBERT WADKINS HARVEY.
